I have just returned from a week in California and the security on flights is pretty strict - no fluids, gases, liquids of any kind.   So I have 18 hours of travel time from Belfast->London->Los Angeles->San Jose and a further 18 hours coming back.

All very well, until you realise that if you are on such long flights with connections you can get pretty sweaty, and you can't take any deoderant with you.    I would like to apologise to the poor girl that sat next to me for 11 hours on the LA->London leg.
